Is this card clonable on xM1, flexDF or maybe both?
Is it 1k card (1 kilobyte of user memory)?
Does it have 4 byte UID (not 7)?
Both yes? Then you can clone it to xM1.
flexDF (same as other DESfire implants) is not supposed to be used for cloning.
Yes and yes
Thank you very much
Yes you can clone it to the xM1 or the upcoming flexM1
